  - Revert "Use proper HEAD ref value when creating project"
    
    The issue fixed by this commit was fixed in a different way on the
    stable-2.14 branch. Reverting this on stable-2.15 will make the merge
    from stable-2.14 easier.
    
    This reverts commit e145010de7911623c98e6111537ffa4997d1a82e.

  - Fix creating missing repository
    
    When replicating to a destination where the repository does not exist,
    updating the HEAD reference failed because the passed reference name was
    not absolute. When this happened, an unchecked exception was triggered
    but never showed in the logs. In fact, the replication logs were showing
    only the message announcing the replication started, but no additional
    information about the success or failure of the operation was displayed.
    
    Avoid this by resolving symbolic references and checking the reference
    is absolute before trying to update the HEAD in the new repository.
